Data striping is like coloring in a picture really fast with markers, but instead of coloring in one section at a time, you color in lots of sections all together.
Imagine a big picture that you need to color in. Instead of starting at the top-left corner and coloring in one section at a time, you decide to color lots of sections at once. You take four markers and start coloring in sections diagonally. For example, you color in the first section with the first marker, then color in the second section with the second marker, and so on.
This is kinda like what data striping does with information on a computer. Instead of saving all the information in one place, it spreads it out across many different places all at once. This makes it faster and more efficient to access the information, because multiple parts of the computer can work on retrieving it at the same time.
Just like coloring in a picture with markers might make it look different (maybe the colors aren't in order or some parts are darker than others), data striping might make the information on a computer look different too. But that's okay because it still works just as well.
